DIP LEDs are the more traditional diode/indicator-light-looking LEDs containing two connecting pins that are through-hole mounted to PCBs (printed circuit boards). DIP LEDs were more widely manufactured prior to the 21st century have higher optical decay, lower CRI, and lower efficacy than the more recent SMD LEDs. However, many DIPs are still used today in many applications popular with hobbyists and DIY enthusiasts through the simple and versatile processing. They are often used in outdoor areas, in contrast to SMD LED, which require a protective sleeve.

The LED pins are for model makers in helicopters or railway tracks just as suitable as for the hobbyist who create his own label, or the gamer who wants to pimp a computer case.

Chip LEDs must always be installed with a series resistor connected to a source or limited continuous current.
